Vertically integrated DMEGC has incorporated changes such as introducing poly-fingers, and defect passivation repair to improve its n-type Infinity solar cell technology, shared the company’s Product Manager for Southern Europe at DMEGC, Alejandro Coll Garcia on day 3 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 Conference.
DMEGC currently operates all of its module manufacturing processes with 100% renewable energy and plans to get the same for its cell manufacturing as well as its target to lower its carbon footprint.
For its Infinity RT series of solar cells, DMEGC uses rectangular cells, while for the Infinity series square cells are used. This configuration allows adaptability to different application requirements, explained Coll. DMEGC’s current Infinity solar cell lab efficiency stands at 26.8% which it targets to expand to 27.05% in H1 2025, eventually reaching 28.20% by H1 2028, as per its cell efficiency roadmap.
At the cell level, Coll said his company has incorporated some changes like poly-fingers, defect passivation repair to improve voltage and reduce cell temperature.
At the module level, it integrates anti-glare glass and light redirection films to lower reflection and enhance light utilization. The reflective brightness of its anti-glare Infinity RT series module was found to be 20% to 30% of the conventional module making these useful for installations near airports, urban centers or even parks.
Currently, DMEGC’s highest efficiency double glass module G12T has 705 W output targeted to be improved to up to 720 W by 2026 with further R&D efforts.
